The required value of the given expression is 6x3 - 13x2 - 13x + 20. Option B is correct.

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the monomial, binomial and trinomial, etc. ax+b is a polynomial.

here,
= (3x² + x - 4)(2x - 5)
= [6x³-13x² - 13z + 20]

Thus, the required value of the given expression is 6x3 - 13x2 - 13x + 20. Option B is correct.

Answer:

The dimensions of the square, that will result in a box of maximum volume is a square with side length of approximately 1.585 inches

Step-by-step explanation:

The  given dimension of the steel sheet are;

The width = 8.5 inches

The length = 11 inches

Let 'x' represent the side length of the squares cut out, we have;

The length of the box formed, l = 11 - 2·x

The width of the box formed, w = 8.5 - 2·x

The height of the box, h = x

The volume of the box, V = (11 - 2·x) × (8.5 - 2·x) × (x) = 4·x³ - 39·x² + 93.5·x

The maximum or minimum volume is found from dV/dx = 0 at max. or min.

dV/dx = d(4·x³ - 39·x² + 93.5·x)/dx = 12·x² - 78·x + 93.5 = 0

Which gives;

x = (78 ± √((-78)² - 4×12×93.5))/(2 ×12)

x = 4.915 or 1.585

When x = 4.915, V = 4 × 4.915³ - 39 × 4.915² + 93.5 × 4.915 = -7.65

When x = 1.585, V = 4 × 1.585³ - 39 × 1.585² + 93.5 × 1.585 = 66.15

Therefore, the local maximum occurs at x ≈ 1.585

Therefore, the dimensions of the square, 'x' that will result in a box of maximum volume is x ≈ 1.585 inches.

Step-by-step explanation:

Answer: Option 3

Step-by-step explanation:

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the concept of trigonometry.

Here, we use the Sine ratio.

Sine 60° = 21/x

===> since sin60° = √3/2

==> x = 21*2/√3

==> x = 42/√3

rationalizing we get as,

==> 42√3/3 ===> 14√3

hence, x = 14√3 units,

so finally, x = 14√3 , option C.) is correct.

[tex]y = \frac{1}{3} x +4[/tex] , [tex]slope, m_1 = \frac{1}{3}[/tex]

Let the slope of the new line be [tex]m_2[/tex]

Since the lines are parallel , [tex]m_1 = m_2[/tex]

                                               [tex]m_2 = \frac{1}{3}[/tex]

[tex](x_1, y_1) = (-3, 1) \ , \ m_2 = \frac{1}{3}\\\\Equation \ of \ the \ new \ line : (y - y_1) = m(x - x_1)[/tex]

                                        [tex]y - 1 = \frac{1}{3}(x -(-3)) \\\\y - 1 = \frac{1}{3}(x +3)\\\\y - 1 =\frac{1} {3}x + 1 \\\\y = \frac{1}{3}x + 2[/tex]

Answer:

1.) Set the data set in the ascending order

2.) Start cancelling out numbers each side, like if u cancel out the first number, then cancel out the last as well.

3.) Keep doing the step 2 until u reach the middle most number.

4.) Sometimes there are 2 middle numbers left, in that case find their average (add both numbers together and divide the sum by 2) which would be ur middle most number.

Answer:

A = 132.25π sq ft

Step-by-step explanation:

C = 2πr

23π = 2πr

r = 23/2 or 11.5

A = πr²

A = 11.5²π

A = 132.25π

Given

perimeter is 62

Side 1 - 3x+5

Side 2 - x+2

Solution,

2(3x+5+x+2) = 62

4x+7 = 31

4X = 24

x = 6

Now substitute the value of x to get the sides

Side one - 3x+5 = 23cm

Side two - x+2 = 8cm

Answer- the length of the longest side is 23 cm

Answer:

625

Step-by-step explanation:

Convert 15300 to a percent,

We can convert it to it's lowest fraction,

120, and to find the percent just multiply it by 5 on top and bottom,

120 ×5×5

which equals, 5100

Then take the percent as a decimal, 0.5 and multiply it by 12500,

12500×0.5 which would give you: 625

The inequality equation is x ≥ ( by - c - d ) / a

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

by - d ≤ ax + c    be equation (1)

On simplifying the equation , we get

Subtracting c on both sides of the equation , we get

by - d - c ≤ ax

And , ax ≥ by - d - c

Divide by a on both sides of the equation , we get

x ≥ ( by - c - d ) / 2

Hence , the inequality is x ≥ ( by - c - d ) / a

Answer:

28.26 cm^2

Step-by-step explanation:

Mathematically, we have the area of a sector as;

theta/360 * pi * r^2

theta is the angle subtended at the center of the circle by the sector which is 90 degrees

r is the radius of the circle given as 6 cm

Substituting these values;

90/360 * 3.14 * 6^2 = 28.26 cm^2
